This crusading king was a living embodiment of the Christianity of the time: he lived for the welfare of his subjects and the glory of God. His father was Louis VIII, of the Capet line, and his mother was the redoubtable Queen Blanche, daughter of King Alfonso of Castile and Eleanor of England. Louis, the oldest son, was born at Poissy on the Seine, a little below Paris, on April 25, 1214, and there was christened. Much of his virtue is attributed to his mother's care, for the Queen devoted herself to her children's education. Louis had tutors who made him a master of Latin, taught him to speak easily in public and write with dignity and grace. He was instructed in the arts of war and government and all other kingly accomplishments. But Blanche's primary concern was to implant in him a deep regard and awe for everything related to religion. She used often to say to him as he was growing up, "I love you my dear son, as much as a mother can love her child; but I would rather see you dead at my feet than that you should commit a mortal sin."

In May, 1234, Louis, then twenty, married Margaret, the oldest daughter of Raymond Beranger, Count of Provence. They had eleven children, five sons and six daughters. This line continued in power in France for five hundred years. In 1793, as the guillotine fell on Louis XVI, it will be recalled that the Abbe Edgeworth murmured: "Son of St. Louis, ascend to Heaven!"

​August 25: St Louis King of FranceO God, who brought Saint Louis from the cares of earthly rule to the glory of a heavenly realm, grant, we pray, through his intercession, that, by fulfilling our duties on earth, we may seek out your eternal Kingdom. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.
